Correctly styling Android Home Widget size

I try to display up to three elements in my Home Widget according to how many rows a user expanded the widget to.

So the height of each element should be the height of one row. The main goal would be that it looks correct on every device.

This is my layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/shape_roundedcorners_white">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/article1"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:orientation="horizontal"
        android:layout_margin="@dimen/widget_margin"
        android:background="#0000ff">

        <ImageView
            android:id="@+id/article1img"
            android:layout_width="35dp"
            android:layout_height="35dp"
            android:gravity="center"
            android:layout_gravity="center"
            android:layout_marginRight="15dp"
            android:layout_marginLeft="10dp"
            android:src="@drawable/ic_notifications" />

        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:layout_margin="@dimen/inner_widget_margin">

            <TextView
                android:id="@+id/article1Title"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:contentDescription="@string/appwidget_text"
                android:gravity="left"
                android:text="@string/appwidget_title"
                android:textColor="#000000"
                android:textSize="14sp"
                android:textStyle="bold"/>
            <TextView
                android:id="@+id/article1Text"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:contentDescription="@string/appwidget_text"
                android:gravity="left"
                android:text="@string/appwidget_text"
                android:textColor="#000000"
                android:textSize="12sp"/>
        </LinearLayout>

    </LinearLayout>

                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:contentDescription="@string/appwidget_text"
                android:gravity="left"
                android:text="@string/appwidget_text"
                android:textColor="#000000"
                android:textSize="12sp"/>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

with

<dimen name="widget_margin">8dp</dimen>
<dimen name="inner_widget_margin">2dp</dimen>

and

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid
        android:color="#ffffff"/>
    <corners
        android:radius="12dp"/>
</shape>

I read here that the height of one row should be about 40dp which is why I set my article1 - Layout to 40dp and my info to

<appwidget-provider
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:initialKeyguardLayout="@layout/news_widget"
    android:initialLayout="@layout/news_widget"
    android:minHeight="40dp"
    android:minWidth="300dp"
    android:previewImage="@android:drawable/ic_menu_add"
    android:resizeMode="horizontal|vertical"
    android:updatePeriodMillis="2700000"
    android:widgetCategory="home_screen">
</appwidget-provider>

But the result I get looks like this, having the widget on minHeight:

So obviously the height of one element in my layout differs a lot to the height of one grid-row on the screen.

What am I doing wrong or what is the canonical approach to solve my problem?
